Abstract: PURPOSE:To enable a voltage which is four times larger than a power supply voltage to be generated by providing a fourth capacitor in which a negative pole side, where an addition voltage and a power supply voltage of a charge of first and third capacitors are applied at a second timing which is generated alternately with a first timing is grounded. CONSTITUTION:In the first step of a circuit, capacitors C1, C2, and C3 are connected between each power supply terminal 1 and a ground, thus enabling Vcc voltage to be charged at each. Also, since capacitors C5 and C6 are loop- connected and a charge of the capacitor 5 is inverted and transferred so that the capacitor 6 becomes positive at the ground side. Also, in the second step, the capacitors C1-C3 are connected in series between the power supply terminal 1 and a capacitor C4 and a voltage of 4Vcc which is obtained by adding a voltage of Vcc of the power supply terminal 1 to a total of the charge, is charged with the ground side as a negative. Also, the capacitors C1-C3 are connected in series also between the power supply terminal 1 and the capacitor C5 and a voltage of 4Vcc which is obtained by adding the voltage Vcc of the power supply terminal 1 to a total of the charge, is charged with the ground side as negative.

Butadiene is then introduced thereinto and the Diels-Alder reaction is carried out for 40hr. The solvent is subsequently distilled off to obtain a reactional product of formula I. To this reactional product, 50% nitric acid and ammonium metavanadate as a catalyst are added and the resultant mixture is heated in a water bath at about 50 deg.C to oxidatively decompose the double bond. Thereby, alpha,alpha-carboxymethylglutaric acid of formula II is obtained and the resultant compound is converted to a dicarboxylic acid monoanhydride of formula III by a dehydration reaction. Further, the resultant compound is treated with phosphorus pentachloride as necessary, thus producing the objective carboxylic acid derivative of formula IV (R<1> is OH or Cl; R<2> is COOH. Or, CO-O-CO may be formed by condensation of both of two R<2>s).
